In simple words: This procedure checks blood flow in your dialysis access point (like a graft or fistula) to make sure it's working well and prevent clots.The doctor uses a special dye and measures how it flows through your access.

This code represents a hemodialysis access flow study conducted to ascertain the blood flow within grafts and arteriovenous fistulae. The study utilizes an indicator dilution method, involving the introduction of an indicator substance into the bloodstream and subsequent measurement of its concentration downstream to calculate blood flow.

Example 1: A patient with a newly created arteriovenous fistula undergoes a flow study to assess its initial functionality and ensure adequate blood flow for dialysis., A patient with a history of clotting in their dialysis graft undergoes a flow study to evaluate the current blood flow and identify any potential obstructions., A patient experiencing decreased dialysis efficiency undergoes a flow study to assess the patency of their vascular access and determine if flow issues are contributing to the problem.

Documentation should include the method used for the flow study, the results of the measurements, and any interpretation or recommendations based on the findings.Details about the patient's dialysis access, such as the type of access (graft or fistula) and its location, should also be documented.
